File extensions help computers locate correct application for specific files.

These file extensions are also beneficial for us. By simply looking at the filename, we can determine what type of information is stored to that and what applications can open these files.

These file extensions make the work of the computer easy. Once there is no application associated with the file, then the computer will immediately ask the users assistance to help look for the source files.
